CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 324,714, dated August18, 1885.

Application filed April 28, 1885. (No model.)

To all whom it may concern:

Be it known that I, ROBERT It. llIARSH, a citizen of the United States,residing at Owosso, in the county of Shiawassee and State of Michigan,have invented certain new and useful Improvements in Car-Brakes; andldohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings, tomaking a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings represents a portion of a freight car with myimproved brake I 5 mechanism connected thereto, and Fig. 2a

detail view of a portion of the brake mechanism.

The present invention has relation to certain new and usefulimprovements in means 2o for automatically operating the brakes offreight-cars, and the object thereof is to improve and simplify themechanism, whereby a train of freight-cars can be as easily controlledas the passenger-trains can with their steam or air brakes; and theinvention consists in the details of construction, substantially asshown in the drawings, and herein after described and claimed.

In the accompanying drawings, A represents the end of a freight'ear,provided at its bottom with a flanged friction-pulley, B, supported in asuitable hanger, a. Around ,the under side of the pulley B passes achain, 6, connected at one end with the usual car- 5 brake, and at theopposite end with a short rod, 0, which passes up through a guidestaple,d. To the upper end of the rod 0 is attached one end of a chain, c, saidchain extending up and around a Windlass, 0, pro- 0 vided with aratchet, f, with which engages a pivoted pawl, The Windlass O is keyedor otherwise similarly connected to the outer end of a longitudinal rod,D, having its bearings in suitable boxes, h, upon the roof of the car.

To the extreme end of the rod D, upon the outside of the Windlass O, isrigidly secured a weighted lever, E, and to the opposite or inner end ofthe rod, and at right angles thereto, is attached an arm, F. This arm isof sufficient length to extend to the side of therunningboard iof thecar, and is provided at its free end with a button, 70, and upon itsunder side is provided with a spring, Z.

A trip-lever, G, which retains the arm F in a set position, passesthrough a guide, 171, secured to the edge of the runningboard t, and isoperated by an arm, n, to which the end of the trip-lever is pivoted,said arm a being in turn pivoted to the running-board (0 or otherconvenient part of the car top or roof. To the free or upper end of thearm a is attached a cord or rod, 19, provided with a snap, r, or othersimilar device, for connecting it with the bell-rope H of the trainofcars.

In setting the brake mechanism the arm F is brought down to the positionshown in Fig.

1 and the trip-lever G forced back so that the end thereof will bedirectly over the button 70. 7c

When it is desired to put on brakes, by pulling on the bell. cord orrope H, the trip lever G is drawn back from contact with the H buttonIt, and the weighted lever E, by its gravity, will descend-and turn theWindlass O, winding thereon the chain c, and bringing the brakeshoesinto action.

The spring Z assists in throwing up the arm F when released by thetrip-lever G, and the button It on said arm renders it more easily 8ooperated.

Should it not be desirable to use a bell-rope, the mechanism can beoperated by hand, and the brake-operating mechanism can be connected toeach. end of the car.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. A brake mechanism consisting of awindlass, ratchet and pawlconnecting with the brakes, a weighted lever for operating the Windlass,and a tripping device for setting and tripping the mechanism,substantially as and for the purpose set forth.

2. In a mechanism for operating the brakes of cars, consisting ofaweighted lever, awindlas ratchet and pawl attached to the brakes bysuitable chains, a rod to which the Windlass is seemed, provided with anarm, in combination with a sliding trip-1ever, substantially as and forthe purpose specified.

3. In a brake mechanism, arod provided at one end with a Windlass andWeighted lever, and at the opposite end with an arm having a button andspring, in combination with a triplever, substantially as and for thepurpose described.

In testimony that I claim the above I have to hereunto subscribed mynamein the presence of two witnesses.

ROBERT R. MARSH.
